Preheat oven to 350°F (175°C). Grease your loaf pan like you mean it.
In a large bowl, mash bananas until they resemble your social battery—slightly mushy.
Stir in oil, sugar, milk, and vanilla. Combine until smooth and dramatic.
In a separate bowl, whisk flour, baking soda, salt, and cinnamon.
Add dry mix to the wet ingredients. Stir just until combined—no overmixing, we’re not angry.
Pour batter into the prepared pan and smooth the top like your best contour.
In a small bowl, mix streusel ingredients with a fork or fingers until crumbly and irresistible.
Sprinkle streusel evenly over the batter like you’re seasoning your ex’s karma.
Bake for 55 minutes, or until a toothpick comes out mostly clean.
Cool in the pan for 10 minutes, then remove and cool completely.
Slice, serve, and pretend it’s the first thing you’ve eaten all day (we won’t judge).
